Maybe the dreaded 58? 

10/10B (with the 10A going stand alone as the 48)

Probably not the 6 since it Interworks with the 12 also they recently got the upgrade with the Daimler Lites.
58 maybes but doubt that since they only just got the Geminis.
Never knew about that 48, depends on the PVR.

Only i can think of is the 57.  Would be a major upgrade
